(Denis is also sort of the namesake for the Parisian hill Montmarte where he’s supposed to have been put to death: “mountain of Mars” in heathen times, it Christianized to mons martyrium, “Martyrs’ Mountain”.)

While many Christian martyrs carry the instruments of their martyrdom in iconography, and a few others roll with the bits of severed flesh exacted by those martyrdoms, Denis is only the most notable of an entire designated sub-class who carry their own heads: cephalophores.
